1、Designation: D6092 14Standard Practice forSpecifying Standard Sizes of Stone for Erosion Control1This standard is issued under the fixed designation D6092; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision.

2、A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1.

Summary of Practice4.1 The design team shall establish the size and mass ofgraded quarry stone using accepta

If using standardsizes, the design team shall select the appropriate gradation;this might require selecting the next larger size, therebycreating an over-designed struct

Added cost may result due to theincreased volume of stone required, and in transporting andplacing the additional stone at the project site. The costeffectiveness of using “standard grading” versus “non-standardgrading” always should be evalua

19、ted, and standard gradingsused whenever possible.5. Significance and Use5.1 The standard size designations listed in this practice areprovided so that the design team, consumer, and the producerhave a common reference in sizing stone materials used inerosion control. The design team should assign a

20、materialssurvey, and rock quality testing series to determine whichquarry sources may have suitable in-place rock and performsuitable blasting and processing procedures to produce therequired gradations. The design team must recognize the factthat not all sources are capable of or willing to produce

21、 therequired gradations. Only those sources listed by the designteam should be considered for construction of the project.5.2 The standard size designations provided in this guide aresuitable for protective surfacing and structures designed forerosion control. These sizes are for typical structures

22、such asjetties, revetments, groin baffles, bulkheads, lining fordrainage/irrigation ditches and for intake or outlet facilities,bridges and stream channel banks, gabions, and slope protec-tion for earth embankment and rock-fill dams.5.3 The design selection of stone sizes, durability,placement, filt

23、er/bedding materials, or geotextiles, steepness ofslopes for placement, and layer thickness are beyond the scopeof this guide.6. Manufacture6.1 The standard size designations of quarried stone forerosion control in this guide may be produced by any suitablecommercial quarrying method, and by the use

24、 of any type ofsizing device, shape or size of plant grizzly or screen openings,or combinations thereof, necessary to produce the requiredsizes within the gradation limits specified in Section 7.6.2 Stones shall be hard, angular to subangular, and of suchquality that they will not disintegrate on ex

25、posure to water orweathering during the designed life of the structure. The stoneshall be free from fractures, shale partings, deleteriousmaterials, and overburden soil.
